You need to trim brass consistently but aren't sure if a fixed bench tool or a portable universal unit fits your workflow. This breakdown compares the Hornady Cam-Lock and Lyman Universal Trimmer so you can stop guessing.
In short: The Hornady Cam-Lock wins for most reloaders who prioritize precision and batch speed, using a fixed bench mount and lever lock. The Lyman Universal Trimmer is better for beginners or those with limited bench space, offering portability without needing shell holders.

The differences at a glance
The two tools approach case trimming with different philosophies. One is a fixed precision machine; the other is a portable, all-in-one utility tool. The table below highlights the core distinctions to help you decide quickly. It helps to understand rotary trimmer 2 before going further.
| Feature | Hornady Cam-Lock | Lyman Universal Trimmer |
|---|---|---|
| Design | Bench-mounted | Handheld/Portable |
| Case Holding | Requires Hornady shell holders | Integrated internal collets |
| Cutter Adjustment | Micro-adjustable (.001″) | Standard manual adjustment |
| Best For | High-volume precision | Occasional use or small spaces |
Build and case retention system
The Hornady uses a cam-action lever to lock the case into a rigid position. This ensures the case stays perfectly square to the cutter during the cut. The Lyman uses a simpler collet system that you expand or contract to hold the case. Both work, but the mechanism changes how consistent your trimming can be.
The Hornady is a dedicated machine. It is built to be bolted to a bench and used repeatedly. The Lyman is designed to be picked up, used, and put away. It does not require a permanent installation footprint.
Hornady wins on build quality for fixed stations. The Lyman wins on portability. If you need a tool that moves with you or stores in a drawer, Lyman is the only option.
Pro tip: Hornady shell holders are usually required for the Cam-Lock. Check that you have the correct size for your brass necks before purchasing the trimmer.
The cam-lock mechanism here provides the rigid retention that the Hornady system is built around.

Accuracy and consistency across batches
When trimming hundreds of cases, minor variations in case placement add up. The Hornady’s micro-adjustable cutter lets you set the length precisely and repeat that setting for every case. The Lyman’s adjustment is functional but less refined for extreme tolerances.
For most handloaders, the difference is negligible. For competitive shooters or those trimming for high-precision optics, the Hornady offers a tighter margin. The Lyman is perfectly adequate for standard hunting and target loads. There is more on fa system comparison review in a separate guide.
Hornady wins on raw accuracy. The Lyman is sufficient for general reloading. Choose the Hornady if you cannot tolerate any variance in case length.
The Lyman Universal Trimmer provides reliable trimming for standard loads without the need for shell holders.

Speed and workflow efficiency
Speed depends on how you prep your brass. With the Hornady, you insert the case, lock the lever, and cut. The motion is rhythmic and fast once you are in a groove. The Lyman requires you to hold the case against the cutter and twist the handle. It is slower but does not require a second station.
If you are doing 50 cases at a time, the Hornady’s fixed setup saves time. If you are doing 10 cases, the Lyman’s ease of use makes it faster to set up and tear down. There is no ‘best’ speed; there is only the best speed for your batch size.
Hornady wins for high volume. Lyman wins for small, infrequent batches. Match the tool to your typical reloading session length.
Pro tip: You can use a power drill adapter with many bench trimmers to increase speed further. This is not possible with the handheld Lyman design.
Which should you buy?
- Buy the Hornady Cam-Lock if you have dedicated bench space, reload high volumes, and want the highest possible consistency. It requires shell holders.
- Buy the Lyman Universal Trimmer if you have limited space, reload occasionally, or want a tool you can easily move. It includes pilots for most calibers.
- Buy both if you do both heavy volume and occasional mixed batches, but this is rarely necessary for one bench.
The bottom line
The Hornady Cam-Lock is the better tool for most dedicated reloaders who value precision and throughput. The Lyman Universal Trimmer is the right choice if space is tight or you reload infrequently. Get the Hornady if you plan to trim over 50 cases in a session. For the detail, see our notes on trim pro-2 vs cam-lock.

Frequently asked questions
Does the Hornady Cam-Lock work with RCBS Shell Order?
No. The Hornady Cam-Lock uses proprietary Hornady shell holders to hold the case in place. You cannot use RCBS Shell Order holders or universal holders with this trimmer. You must purchase the specific Hornady holders for your caliber.
Can I use the Lyman Universal Trimmer on a drill press?
No. The Lyman Universal Trimmer is designed to be handheld. It lacks the mounting holes and stability required for a drill press. For powered trimming, look at bench-mounted models like the Hornady or RCBS Trim Pro.
Which trimmer is easier for a beginner?
The Lyman Universal Trimmer is generally easier for beginners. It does not require a separate shell holder system and is more forgiving if your bench space is limited. The Hornady requires more setup and specific parts but offers better long-term performance.
